Supercharger pulley came off

[xxburkettxx07]

98gtp was driving yesterday gave it some, gas next thing I know I hear a few clunks n lost boost n most of power...look under hood the supercharger pulley is gone, and only the shaft appears to be fine.. anyone ever had the pulley come off the shaft...it was a rebuilt snout with a3.4 pulley all bought from zzp and they pressed the pulley on the snout last year..

Mind blowing wtf would cause that it's been a year almost exactly now..it spins freely n when I give the car a lil gas it spins...it was noisy as hell tho..car is nice n quite now. Could I need new rotor needle bearings? When I spin the shaft it feels smooth n play at all..n it had new coupler Could the needle bearings be the reason it was so noisy?? Are they hard to replace

look under the engine a top the splash shield for the pulley, near the motor mount. if its not down there look again back where it popped off. it maybe cracked. the outer bolt is also gone.

the needle bearings can make noise but most of the time you will get resistants in the rotors when spinning, to replace you have to take off the front drive pull the rotors, tap and insert grease fitting so you can press out the old bearings, although at this point I would be interested to see if you have any play in the rotors and how the inside of the case looks

I think I have one laying around

[Scottydoggs]

if the sc is making sounds now, its broken. either the coupler or bearings. bearings are not so easy to just change.

hand turn the sc see if you hear any thing.

most wont have a extra bolt. jy time or dealership.

Last year when I installed the
supercharger the coating was all good still

[xxburkettxx07]

It don't make any sounds right now it's dead silent lol jk but when I spin it by hand no resistance it spins as it should n extra play or anything
